Well you can use indexOf for validation:
String.indexOf
Availability
Flash Player 5.
Usage
myString .indexOf( substring, [ startIndex ] )
Parameters
substring An integer or string specifying the substring to be searched for within myString .
startIndex An integer specifying the starting point in myString to search for substring. This parameter is optional.
Returns
The position of the first occurrence of the specified substring, or -1.
Description
Method; searches the string and returns the position of the first occurrence of the specified substring . If the value is not found, the method returns -1.
so for example to validate an email:
function validateEmail(emailText:String){
if (emailText.indexOf("@")!=-1 && emailText.indexOf(".")!=-1){
//place code for valid email here
}else{
//place code for invalid email here
}
}
Sexcellent idea, thank you.
